Title:
Intel Iris Xe Graphics: System freeze with kernel 6.8.0-48 on
TigerLake (Ubuntu 22.04.4 LTS)

Status in linux package in Ubuntu:
Confirmed

Bug description:
Description:
After upgrading to kernel 6.8.0-48-generic (version 6.8.0-48.48~22.04.1, via unattended upgrade on Nov 1st, 2024), my system experiences complete freezes requiring hard reboot.

Expected behavior:
- System should remain stable and responsive
- Graphics should function normally

Actual behavior:
- System freezes completely within minutes of booting
- Requires hard reboot (power button hold)
- Logs show error: "i915 0000:00:02.0: [drm] *ERROR* The master control interrupt lied (DE PIPE)!"

System information:
- Ubuntu version: 22.04.4 LTS (jammy)
- Kernel package: linux-image-6.8.0-48-generic (6.8.0-48.48~22.04.1)
- Hardware: Dell laptop with Intel TigerLake-LP GT2 [Iris Xe Graphics]
- Previous kernel 6.8.0-47-generic worked correctly
- Current workaround: Using kernel 5.15.0-124-generic which works properly

Steps to reproduce:
1. Boot with kernel 6.8.0-48-generic
2. System freezes within minutes
3. No specific trigger action required - happens during normal use
